SPECIFICATION forming part. of Letters Patent No. 482,578, datedSeptember 13, 1892.

Application filed .Tune 20, 1892. Serial No. 437,355. (No model.)

T all whom. t may concern:

Be it known that I, KARL KIEFER, a citizen of Germany, residing atCincinnati, in the county of Hamilton and State. of Ohio, have inventedcertain new and useful Improvements in Funnels; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to whichitappertains to make and use the same.

My invention relates to tunnels for filling vessels, principally adaptedforbottles, that will be automatically closed when the liquid rises to acertain elevation therein.

My invention is hereinafter fully described,

illustrated in the drawings, and specifically pointed out in the claims.

Referring to the accompanying drawings, wherein like letters ofreferencepoint out similar parts on each ligure, FigureI is averticalcentral section of a funnel inserted within the neck of a bottle inposition for passing liquid therein. Fig. II is a similar view showingvalve closed when the bottle is filled up to a desired elevation. Fig.III is a top View of preferred form of funnel. Fig. IV is an enlargedcross-section on line a cof Fig. I.

In the drawings, A is the funnel; B, cornbined inlet and valve tube; C,tubular openended cup -shaped chamber surrounding lower end. of tubularstem D, having lower outlet-aperture c, through which the fluid from thefunnel will flow into the vessel, as indicated in Fig. I bydownwardly-pointing arrows. The wall of cup C is concentric with tube Band adapted to readily move therein vertically, in a manner and for apurpose presently pointed out.

D is a tubular valve-pipe reaching full length of the tube B, its upperend beingpermanently attached to press-button 7c, its lower end carryingvalve 71. to seal the open end of tube B when the bottle F is filled toa given elevation. The pipe D extends within the center of tube B and ismaintained therein vertically by passing through orificed fixed disk cl,adj usted in horizontal position within tube B at the upper sectionthereof, said disk also serving as support for end of coiled spring g.Pipe D furnishes means for outward passage of air from within vessel Fas it is gradually filled with fluid. At its lower end neXt above valveh said pipe has a lateral open-ended air-inlet branch d', and near itsLipper end is an outlet f, for a purpose that will be readilyunderstood. Above the branch d the pipe D carries a cup C, open at itsupper end, surrounding said pipe circumferentially and havingoutlet-aperture c.

E is an oriced cork movable on the tube B, outwardly shaped to conformto theinside- B into two sections, the upper one of which is providedwith coiled spring g, surrounding pipe D, its lower end resting on saiddisk d, its upper end bearing against the lower flat end of push-buttonk. By compressing said push-button the pipe D will be projecteddownwardly, removing valve h, whereby the device will be in the positionshown in Fig. I, ready for action as the bottom of the valvechamber Cwill be open for downward outflow of liquid through its orifice c andupward outlet of air through brauch el', as indicated byoppositely-turned arrows. Normally the device after the cork has beeninserted within mouth of the vessel will be in position illustrated inFig. II.

In Fig. IV the bottom of the cup C is shown at t'. Z is the handle.

It is my intention to have divers sizes of tunnels, each adapted tocontain a given quantity of liquid of required volume to supplyarespective vessel F up to a given height or to place graduateddenominative scale thereon for like purposes.

The funnel main chamber is not a oomplete cone as commonly employed indevices of analogous character, buta section thereof. It may be a fullhalf, as illustrated in Fig.. III; but I do not limit myself to theprecise shape shown. The straight-back wall w composee a hemisphericalupper opening; but it may be nearer to or farther from the truediametrical line of a circle without departing from the scope andpurview of my invention; but in all forms said wall is fiat to compose abearing for the vertical tube B.

From the foregoing description, in connection with the drawings, thenature, object, and practice of my invention will be readily understoodby all familiar with the special branch of art to which it is allied.

Its operation may be thus brie fly described: The funnel is filled up toa height indicated by a scale shown thereon to be a required quantityeither before or after being inserted within the vessels mouth andreplenished as necessary. Its contents will fiow through opening a, andrise within the tube B up to disk d. When adj usted in position shown inFig. II, the button 76 is pressed downwardly and the device assumes theposition shown in Fig. I. As the fiuid passes into the vessel thecompressed air will fiow upwardly through inlet branch d and bedischarged through opening f into the upper section of tube B above diskd, and from thence through outlet e of said tube.

Having thus fully described my invention and the manner of itsoperation, what I claim, and desire to secure by Letters Patent of theUnited States of America, is-

1. A funnel for filling bottles or similar receptacles, consisting of asection of a cone having a straight back, to which is attached,vertically, tube B, having orifice a opening into and communicating withthe lower end of the funnel, said tube provided with valve-pipe D,extending the full length thereof, and the disk d, having orifice inwhich said pipe is mov able, said oriticed disk being permanentlyadjusted near the upper end of tube B, the plpe D, carrying at its lowerextremity valve h, and the open-ended cup C above said valve, integralwith said pipe and surrounding it concentrically, havingeduction-orifice c, all in combination with hollow stem of theValvepipe, having open-ended branch d and upper aperture f, as and forthe purpose intended, substantially as described.

2. In a funnel having its body formed of a' section of a cone and fiatback w, Vertical tube B, hollow pipe D within the tube, adj usted tomove reciprocatingly in vertical directions within said tube, the pipeD, having at its lower end valve h and at its opposite end push-button7c, spiral spring g under the push-button, bearing upwardly against theunder surface of said push-button, orificed disk d, horizontallyadjusted within tube B at the opposite end of the spring, all incombination with lower air-inlet d and upper air-outletf, and valve-cupC, integralv with and surrounding the lower end of pipe D, concentrictherewith and movable vertically within tube B, substantially asdescribed.

In testimony that I claim the invention above set forth I affix mysignature in presence of two witnesses.

KARL KIEFER.
